NFL Playoff Schedule 2013: Key Matchups for Sunday's Games

Sunday's NFL playoff games aren't quite as sexy as the Saturday games, but a Super Bowl participant could be playing in one of the two games.

Here is the schedule for Saturday and Sunday's games:

Saturday's Games

No. 4 Baltimore Ravens at No. 1 Denver Broncos

Sports Authority Field at Mile High, 4:30 p.m. ET, CBS

No. 3 Green Bay Packers at No. 2 San Francisco 49ers

Candlestick Park, 8 p.m. ET, FOX

Sunday's Games

No. 3 Houston Texans at No. 2 New England Patriots

Gillette Stadium, 4:30 p.m. ET, CBS

No. 5 Seattle Seahawks at No. 1 Atlanta Falcons

Georgia Dome, 1 p.m. ET, FOX

The Houston Texans travel to Gillette Stadium in an effort to upset the New England Patriots. The Seattle Seahawks will be looking to grab another playoff road win at the Georgia Dome against the Atlanta Falcons.

Here are the key matchups that will determine which teams advance to the conference title games.

Depending on which gap Wilfork tries to plug, Texans' center Myers will get some help trying to keep Wilfork from collapsing Arian Foster's inside running lanes.

Wilfork's ability to stuff the run will be huge in this matchup. If he can be the factor against the run that he was in the team's first meeting, it will be difficult for the Texans to win.

Foster was held to only 46 yards on 15 rushes in the Patriots' 42-14 loss. You can credit Wilfork for the Texans star's subpar day.

Although Wilfork only had four tackles, his ability to hold ground and penetrate, breaks down a running game.
